Only a trained maintenance expert should perform the following items.
z Replace hydraulic hoses
z Replace or rebuild hydraulic cylinders as required.
z Replace or rebuild pumps / motors as required.
z Check hydraulic cylinder rod and rod end (threads) for deformation or damage.
z Check cylinder mount for looseness and damage.
Relocating or changing components may cause problems. Each component in the
system must be compatible; an undersized or restricted line will cause a drop in
pressure. All valve, pump, and hose connections should be sealed and / or capped
until just prior to use. Air hoses can be used to clean fittings and other components.
However, the air supply must be filtered and dry to prevent contamination.
Contamination is the most frequent cause of malfunction or hydraulic equipment.
